[Bug tree-optimization/16131] New: internal compiler error: in create_tmp_var, at gimplify.c:361

[gerald at pfeifer dot com]

Recent changes (< 48 hours) on mainline cause GCC to ICE when compiling the
well-known test case from PR8361:

% gccvs  8361.ii generate.C: In member function `bool  
MODEL_GENERATOR::onlyOneUndefAtomGreaterThanUpperGuard(constAGGREGATEATOM&,
constGINTERPRET&) const':
generate.C:3233: internal compiler error: in create_tmp_var, at gimplify.c:361

(This testcase is http://gcc.gnu.org/bugzilla/attachment.cgi?id=4415&action=view)

Richard^2, I'm afraid this was triggered by one of your recent changes.

I almost think this is Kenner's change as it causes a regression in the C++ testsuite which he said it 
did.

    I almost think this is Kenner's change as it causes a regression in
    the C++ testsuite which he said it did.

It's likely to be my change, but if my memory is correct the testsuite
regression causes an ICE elsewhere (verify_stmt, I think).
